BA03CC0FP-E2 Equivalent & Substitute Parts

Part Overview

The BA03CC0FP-E2 is a linear voltage regulator IC manufactured by Rohm Semiconductor, classified as a Power Management (PMIC) component. This positive fixed output regulator delivers 1A at 3V and operates across an input voltage range of up to 25V. The device is housed in a TO-252-3 (DPAK) surface mount package and is currently in active production status with 2300 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitute parts for the BA03CC0FP-E2 are qualified based on the following critical parameters:

Fixed output voltage of 3V
Positive output configuration
Surface mount TO-252-3 (DPAK) package compatibility
Operating temperature range of -40°C to 125°C
ROHS3 compliance and REACH unaffected status
Active product status

The identified substitutes are LP2950CDT-3.0/NOPB, LP2950CDTX-3.0/NOPB, and LP2950CDT-3.0RKG. These parts share the same output voltage specification and package form factor. However, the substitute parts operate at reduced output current ratings (100mA versus 1A) and feature different input voltage maximums and quiescent current specifications. Substitution is valid only when the application circuit does not require the full 1A output current capability of the primary part.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the primary BA03CC0FP-E2 device.

The LP2950CDT-3.0RKG (onsemi) variant offers the lowest dropout voltage at 0.45V @ 100mA and is supplied in Tape & Reel packaging with unlimited moisture sensitivity level (MSL 1), matching the primary part's packaging format and environmental robustness.

The LP2950CDTX-3.0/NOPB (Texas Instruments) includes short circuit protection in addition to over current and over temperature protection, providing enhanced fault tolerance compared to the other LP2950 variants.

Selection between substitute parts should be based on application current requirements, dropout voltage constraints, and specific protection feature needs. The primary limitation of all LP2950 substitutes is the reduced output current rating of 100mA, which restricts their use to applications requiring less than 100mA load current.

Frequently Asked Questions (FAQ)

Q: Can the LP2950 series parts directly replace the BA03CC0FP-E2 in all applications?

A: Direct replacement is valid only for applications where the load current does not exceed 100mA. The BA03CC0FP-E2 is rated for 1A output, while all LP2950 variants are rated for 100mA maximum. Circuit redesign or alternative component selection is required for applications demanding higher output current.

Q: What are the key differences between the three LP2950 substitute options?

A: The LP2950CDT-3.0RKG (onsemi) features the lowest dropout voltage at 0.45V and is supplied in Tape & Reel format with MSL 1 rating. The LP2950CDT-3.0/NOPB and LP2950CDTX-3.0/NOPB (both Texas Instruments) share identical electrical specifications but differ in packaging format and protection features. The CDTX variant includes short circuit protection.

Q: Are all substitute parts pin-compatible with the BA03CC0FP-E2?

A: Yes. All parts use the TO-252-3 (DPAK) package with identical pin configuration: 2 leads plus tab. PCB layout modifications are not required for mechanical substitution.

Q: Do the substitute parts support the same operating temperature range?

A: Yes. All substitute parts operate across -40°C to 125°C, matching the BA03CC0FP-E2 specification.

Q: What is the impact of the higher quiescent current in the BA03CC0FP-E2?

A: The BA03CC0FP-E2 draws 2.5 mA quiescent current compared to 120 µA for LP2950 variants. This 20x difference is significant in battery-powered or ultra-low-power applications where standby current is critical. Applications with stringent quiescent current budgets should retain the BA03CC0FP-E2.

Q: Are all parts equally available in the supply chain?

A: Current inventory levels vary. The LP2950CDT-3.0RKG shows 3096 units in stock, the BA03CC0FP-E2 shows 2300 units, while the Texas Instruments variants show 1496 and 1110 units respectively. Availability should be confirmed for production quantities.
